I got laptop 13 for several month, cycle count 27 but I got 13.9% wear level. lol
How did you get the history?
for windows, that’s powercfg /batteryreport

Done any full change/discharge cycles lately?
You may need to fully discharge it in this case, like won’t turn on without the power adapter discharge.
If that doesn’t improve the readings it may be time to hit up support.
Not necessarily. Most laptops, at least all laptops I used previously, have their lower calibration point at 7% i.e they will either discharge suddenly to 7% or stay at 7% for a long time if the laptop is unplugged and the battery’s capacity meter has drifted
What’s the voltage of the battery at 5% assuming you are not running resource intensive task
Never had one do that at 7% all the laptops I have previously done the full discharge/charge dance with have tended to hang in there below 5%, usually 0 or 1%.
Ideally they should implement an explicit battery re-calibration in the ec like the thinkpads have where it discharges and charges the battery while connected to power.
It is a bit ironic that charge limits that reduce battery wear also tend to make the wear readout look a lot worse than it actually is XD.
Sorry, my memory must be incorrect. Will do my own research in a few days. Stay tuned
Has anybody here got more than 255 cycles recorded on their battery?
My 11th gen 13" battery cycle count seems to have been “reset” and now shows single digit cycles after reaching 255 cycles and while it could be a coincidence I think that value could be a clue (0-255 values per byte).
